CA Successfully Concludes Deferred Prosecution Agreement

Court Dismisses All Pending Charges

ISLANDIA, N.Y.--(BUSINESS WIRE)--May 21, 2007--CA, Inc. (NYSE:CA)
today announced that it has satisfied the terms of the Deferred
Prosecution Agreement (DPA) the Company entered into in September
2004, and that the DPA has expired.

In a filing with the Court, the U.S. Attorney's Office for the
Eastern District of New York (USAO) reported that CA has "complied
with" the DPA, citing the May 1, 2007 report of Independent Examiner
Lee S. Richards III who was appointed under the agreement. As a
result, U.S. Judge I. Leo Glasser has dismissed all pending charges
against the Company.

"The expiration of the DPA is the result of the willingness of the
government to allow CA to operate under a DPA and the strong
commitment by all the Company's employees to take the steps necessary
to meet its requirements. This has been a very healthy process for the
Company," said Lewis Ranieri, chairman of CA's Board of Directors. "We
want to thank our independent examiner for helping CA identify and
address all DPA issues and for helping us strengthen our internal
controls and compliance."

John Swainson, CA's president and chief executive officer, said
the Company remains committed to best-in-class controls and
compliance.

"Our efforts won't stop because we have met the requirements of
the DPA," he said. "We will continue to demand a high level of
transparency, ethical behavior and integrity from our entire
organization. In meeting the terms of the DPA, CA has made great
strides in putting in place the business systems, processes and
procedures that will ensure its ability to grow and generate value for
shareholders, customers and employees.

"We are moving forward with a renewed sense of vigor, enthusiasm
and dedication to becoming one of the world's most successful software
companies," Swainson said. "We can now put this chapter behind CA and
devote our time, energy and passion to our customers and our business.
We have done much over the past two years to set this company on a
course of sustainable growth. In the future, we will do even more."

The DPA arose out of the criminal conduct by certain of the
Company's former executives in failing to record within the proper
quarter revenues associated with certain software license agreements,
and then obstructing the government's investigation of this "35-day
month" practice.
